CHANNELING M'ACHINE.

SPECIFICATION -forming part of Letters'Patent No. 453,999, dated June 9,1891. Application tiled November 20, 1820*.y Serial No. 371,981. (No model.)

To all whom it may concern:

Be it known `that I, ZACHARY T. FRENCH, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Channeling-Machines,ofwhich the following description, in connection with the accompanying drawings, is' a specification, like letters vand figures on the drawings representing like parts.

This invention in channeling-machines has lmore especially lfor its object an improved construction and combination vof y knives therewith, whereby the depth ofthe inner lip which is to be trimmed ol may be regulated at will. v

My .invention consists, essentially, in the a diagonal groove and grooved upon its under side to form a shoulder, of a channel-knife adjustable in vsaid diagonal groove, a clamp therefor, and the longitudinally-slotted trimming-knife placed against the shoulder of the carrier and held in adjusted position by a setstantially as willbe described. y

Figure 1- inelevation shows a sufficient part of'a channeling-machine with my improve- 'ments added to enable my invention to be understood, the usual presser-foot which bears on the upper side of the materialhaving been omitted to better show the knives behind it. Fig. 2 shows the knife-carrier def tached, but with the knives thereon; Fig. 3, an undei` side view of the knife-carrier and its knives. Fig. 4' shows the rear side of thecarrior. Figo showsthe presserffoot detached, and Fig. 6 shows a piece of sole as it will ap. pearafter having beenpassed throughthe The frame-work A, the rotating table or work-support A', thek gears A2- A3, the shaft A4, the edge-gage B, thel edge-slitting blade a, (seeFig. 1) to cut the -slit a inthe edge of rying leverxBare 'andmaybe all as; usual in l formed.

: channeling-machines now in use. The holes 5o 2 2 in practice receive bolts by which to secure io the lever B4 the usual presser-foot E, (see Fig. 5,) which bears on the upper side of the material to be channeled. -The lever B4 has at its rear side (see dotted -lines,-Fig. l) 55 a groove b,in which enters arib b2 on a knifecarrier D, which is secured to the lever BJL by a set-screw D2. This knife-carrier (see Fig.

4) is provided at its rear side with a groove v 3, in which is laid the shank of the channel- 6o knife d,whi'oh cuts the slot din the sole for the production of the inner lip d2, the shank of the said blade being acted upon by a clamp d3, held in place by the screws d4. The knife d is made adjustable inthe direction of 65 its length, so that it may cut a slot which shall extend into the sole and toward its face side to the desired point. The under side of the knife-carrier is groved to leave a shoulder e, against which is placed one edge of the 7o shank of ,the lip-trim mingblade e', employed to trim off the edge of the lip formed by the knife d, leaving the said lip with a uniform edge, aslshown .in Fig. 6. The shank of the knife e ,is slotted, as at e2, for the reception 7 5 I cfa set-screw 4,.by which to hold the said knife inv adjusted position, the saidknife being made adjustable horizontallyin the directionjof its length', to thereby enable more or less of thevthin edge ofthelip d to be cut 8o olf, the removalof the said lip leaving more room for the stitch and obviating the formation of-a ridge. y Priorto my invention I am aware that a. sole has been split in from itsedge, and that 85 part of one of Athe' lips soform'ed has been trimmed or cut .off, as in United StatesPat-- ents No. 254,6121and No.' 68,094, bntprior to my inventionl amfnot aware that the inner channel-lip has groove and groo'vedupon `its. under sideTto for-ina shoulder e,of a "cha'hnel-knifedyadf justable in said -diagonal groovefa clamp ever 'been trimmed as it is v,9o i

therefor, and lLhe longitudinally-slotted trimto this specification in the presence of two sul) ming-knife e', placed against the shoulder e sei'ibing Witnesses. of'the carrier, and held in adjusted position f 1 ,f f i y 3 y by a ,set-screw extended through said slot, to ALUARX l' h RHASH' 5 cut a lip in the sole and trim the edge of the Witnesses:
